PUMPING APPARATUS FOR CONTROLLING OF THE LIQUID SPEED IN A TUBE SYSTEM

摘要

A pump device for flow rate control of liquid in a piping system in which the pump housing sealing engages a pipe of the system, the housing having an axial channel extending parallel to the pipe and communicating at its ends with the pipe via holes in the pipe, a guide member adjacent the upstream hole for guiding a portion of the flow into the pipe, and the rotatable part of a power driven pump mounted on the housing being located in the axial channel for pumping the fluid therein into the pipe through the downstream hole thereby accelerating the liquid flow through the pipe.
